If the ARP is not getting resolved in either of the two workstations, then the following conditions may 
exist:

• General health of the switch or NI.

• Physical link status might not be operational

• MAC address not learned on the port

• ARP request not reaching the switch, which may be possible because:

- The workstation is not sending an ARP request

- The workstation is not able to understand the ARP request

- ARP packet might have got corrupted

- Duplicate IP addresses configured on the workstations in the same VLAN
